Title: Improvements in the lubrication of internal-combustion engines
IPC: F01M5/00
Filed: 1929-12-11
Abstract: 340,119. Lubricating. ALBION MOTOR CAR CO., Ltd. and PARKES, J: D., South Street, Scotstoun, Glasgow. Dec. 11, 1929, No. 37966. [Class 12 (iii).] Controlling flow of lubricant.-A valve A<1> controlling the flow of oil from the lubricating system C of an internal-combustion engine through passages B, D to a selected point or points, such as the cylinder walls or bigends, is maintained open by a spring A<4> when the engine is stopped but is closed when the engine is running by pressure from the system C, the closing movement of the valve being retarded, Lubricant is thus supplied to the selected point immediately the engine is started, but this supply is out off as the pressure in the system C develops. The valve A<1> is constituted by the smaller end of a differential piston working in a cylinder A<2>, A<3>, the outer end of the larger portion A<2> of the cylinder being in communication with the system C through a restricted aperture E and the inner end being in communication, through a restricted aperture F, with an oil chamber G kept full by splash from the crank case. The cylinder A<2>, which thus constitutes a dashpot, may operate with air or other fluid instead of oil.

Title: Manufacture of strippable wallpaper and strippable poster paper
IPC: D06N7/00
Filed: 1971-08-13
Abstract: 1337026 Papermaking ABITIBI PAPER CO Ltd 13 Aug 1971 [28 Sept 1970] 38159/71 Heading D2A A paper base sheet for strippable wallpaper or poster paper is made by simultaneously wetforming a pair of webs, passing them through a press section to bond them together to form the sheet and drying the sheet, the strength of the bond when the sheet is dry being so controlled that one web of the sheet can be stripped from the other. The bond strength is controlled by the pressure in the press section being controlled, by controlled amounts of rosin size being added to the furnish used to form one or both of the webs, and by controlling the refining of the fibre furnish used. The webs are formed on-Fourdrinier wires 14, 16 and are carried by felts 20, 22 to press sections 24 and 26 and they are then passed to a smoothing press 28, a drier 30, and a size press and calenders (not shown). A clay coating may be applied to the sheet to facilitate printing, and after printing the sheet if used for wallpaper is given a clear plastics coating over the print and the unprinted side of the sheet receives a layer of gum. Examples of preferred fibre furnish give percentages of Hardwood Sulphite, Softwood Kraft, Paper Machine Broke and Mill Broke used, and examples of the quantity of rosin size and alum added to the furnish are also given. The amount of rosin size used is such as to give an ink float test result of 400 seconds minimum for the web which will be subject to printing and 800 seconds minimum for the other web, the combined webs having a result of over 1500 seconds. The sheet may be blade-coated during calendering. The bond between the web is such as to give a reading on a Scott Internal Bond tester of 20 to 50 thousands of a footpound per square inch. The printed sheet may be coated by the air-knife method with an enamel coating formed from a water slurry of clay, pigment and binder. The printing is carried out with water based inks applied on a common impression drum from relief patterns on rollers at a plurality of stations. The invention may be used to make gummed strippable labels.

Abstract: 344,102. Combing-machines. NASMITH, J. W., Leegate, Mauldeth Road, Heaton Mersey, Manchester. Dec. 18, 1929, No. 38732. [Class 120 (i).] In a combing-machine of the type wherein the fibre to be combed is held by nippers and in which the tuft is detached and simultaneously drawn through a top comb which penetrates the tuft, the tuft-detaching nip point is caused to move towards the nippers and the top comb to advance in the same direction but over a less distance, the necessary relationship between the detaching nip, and the piecing-roller nip being preserved during the movement. When applied to the detaching means described in Specification 339,301, [Class 120 (i), Spinning, Preparation &c. for], the machine is arranged as shown in Fig. 1. The detaching means comprises a detaching roller D making intermittent contact with the combing cylinder segment 8. The piecing rollers P, P<1> are adjacent to but do not contact with the roller D. The shaft ends of the roller D are housed in bushings engaged by the weight-hook 9 and supported in a forked lever 10 pivoted at 20 on an adjustable lever 21 pivoted at 22. The roller P<1> is carried by a link 14 pivoted at 13 in a slot 12 formed in an extension 11 of the weight-hook 9. The latter is pivoted through a bracket 9a to a lever 15 on the cam-oscillated shaft 16, the top comb 25 receiving its to-and-fro motion from the shaft 16 by means of a short arm 26 on the lever 15 and the linkage 27, 28. The top comb carrier 34 and the top comb lifting lever 32 are both pivoted at 31 on the lever 28, the lifting lever 32 normally resting against a bowl 35 on the weight-hook 9. The rollers P<1>, D and the top comb 25 are shown in Figs. 1 and 2 in their most backward position, i.e. nearest the nippers. On anticlockwise rotation of the shaft 16 the weight-hook 9 moves to the left, the roller P<1> rolls over the lower roller P and the roller D, after first rolling on the cylinder segment 8, is lifted clear therefrom by the lever 10 and moves in an arc about the centre 20. Simultaneously the bowl 35 moves the lever 32 about the pivot 31 and through the screw 33 lifts the carrier 34, the parts assuming the positions shown in Fig. 3.

Abstract: 1,270,170. Making semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 5 Aug., 1969 [6 Aug., 1968], No. 39127/69. Heading H1K. A base region is produced by ion implanting the same region (roughly that of the final emitter zone) of a collector body with impurities of opposite conductivity types and by then heating the structure so that the much faster diffusing impurity (of opposite type to the body) forms a base zone around the implanted area while the slower moving impurity substantially remains in the implanted region to define an emitter zone. At some stage a doped surface zone is provided to give an enlarged portion for contacting the base. The two transistor structure shown is made from 10-20 ohm.cm P-type wafer in which collector sub-layers 204, 206 are formed by arsenic diffusion (from doped silicon powder) or by etching pockets and filling them epitaxially. The epitaxial 0À2 ohm.cm arsenicdoped layer 208A, 208B is then provided. Next, the P-type surface zones 224, 230 are provided, by diffusion or ion implantation of boron or gallium, though they may instead be formed subsequent to emitter and base formation. Acceptors are then implanted uniformly in regions 226, 232 (using B or Ga) and donors of low diffusion coefficient (Sb) then uniformly implanted in the same area. In a subsequent thermal diffusion step the faster moving acceptors move into the surrounding collector zone to form the main parts 224A, 230A of the base zones. Photoresist masking 240 is used during the subsequent provision of a uniformly implanted isolation wall 242.

Abstract: 904,357. Welding by fusion. WESTING- HOUSE ELECTRIC CORPORATION. Nov. 15, 1960 [Nov. 27, 1959], No. 39149/60. Class 83 (4). [Also in Groups XXXV and XXXVII] In metal arc-welding the motor for feeding the electrode has a power supply separate from the welding supply, a relatively flat speed torque curve and is of ample rating to feed the electrode at constant speed whatever the loading on the motor, and the speed of the motor during welding is controllable only by manual control setting the potential impressed on the armature. A three-phase supply L1, L2, L3 feeds a constant potential type power unit connected between the electrode E and the work W. The armature of the feed motor is connected through a rectifier RX a transformer T2 and a variable transformer T1 constituting the manual speed control to one phase 1L1, 1L2 of the three-phase supply which also energizes the field-winding F through a further rectifier. The armature is normally in series with an adjustable braking resistance R2. Operation of an inching push-button 1PB connects the full supply voltage to the transformer T2 to inch the motor at a speed determined by an adjustable resistor R1. To start welding switch SW is closed. Relay 2CR disconnects the braking resistor R2 and actuates 1CR and the shielding gas supply valve SV, and relay M connects up the welding supply. When the arc strikes, relay 3CR completes the armature circuit of the feed motor A which feeds the electrode until the opening of switch SW allows 2CR to fall back and connect up the braking resistor R2. If desired, transformer T2 may be dispensed with. Specification 687,819 is referred to.
